Fertilisation and cell numbers on my cycles
IVF1
1 egg collected
1 egg mature
1 egg fertilised.
Disintegrated before day 2 transfer
IVF 2 - Cancelled
IVF 3
5 eggs collected
4 eggs mature
3 eggs fertilised.
1 embryo abnormal
2 embryos transferred at day 2. Both 2 cells so not great quality.
IVF 4
4 eggs collected.
3 eggs mature
1 egg fertilised
1 embryo transferred at day 2. 4 cells.
IVF 5 - Cancelled.
IVF 6 - Cancelled
IVF 7
5 eggs collected
5 eggs mature
2 eggs broke apart with ICSI
1 egg didn't fertilise
2 eggs did fertilise but 1 was abnormal, leaving one embryo.
My lone embryo was 10 cells at day 3 and a morula at day 4.
Got a call morning of day 5 when I was about to leave home for transfer that it had arrested.
IVF 8
4 eggs collected-lots more follicles this time but issue with injecting trigger
1 egg mature
1 embryo
Arrested the morning of day 3 transfer - never round out how many cells before arrest.
It seems that getting them from morula to blast must be the most complex part for the embryo as that's were they seem to go wrong.
Yours was only 6 cells at day 3 so I guess that's an indication that it perhaps wasn't strong enough anyway, but I had one top quality embryo in IVF 7 that still didn't make it to blast. I have read somewhere that a high percentage make it from fertilisation to day 3. But then only a smaller percentage make it from day 3 to day 5. (Can't remember exact figures).
Then again, you hear so many stories of women who do have embryos make it to day 5 blast, yet they still don't implant. There's just no guarantees.
I am on day 2 of my cycle so I will start my estrogen tablets on day 20 in prep for IVF next cycle. Reading all the stories (and failures) of women going through IVF on here at the moment has me a bit hesitant about putting myself through this emotional torture again.
